STRUCT BRCMF_CONFIG_AF_PARAMS(9)

💅 struct brcmf_config_af_params

okay so bestie, welcome to the Kernel API Manual (kernel docs, but make it fashion). Today's main character is struct brcmf_config_af_params — the Action Frame Parameters for tx. yes that's the whole vibe, it's a little struct that carries the settings you need when you're firing off an action frame. 🎀

✨ NAME ✨

struct brcmf_config_af_params — Action Frame Parameters for tx. literally just the config bundle for transmitting action frames, periodt. 💖

🌸 SYNOPSIS 🌸

struct brcmf_config_af_params {
    s32 mpc_onoff;
    bool search_channel;
    bool extra_listen;
 };

three members, all baddies, all doing their own little job. 🦋

okay let's meet the cast:

• mpc_onoff — bestie, this one is here for one reason: to make sure the action frame actually gets sent successfully, we have to turn off mpc. the values are the whole personality: 0 means off, 1 means on, and (-1) means do nothing. yes, negative one is the "no thoughts, head empty" option 🙈.
• search_channel — 1 means search the peer's channel so we can send the af. that's it, that's the flag ✨.
• extra_listen — keeps the dwell time around so we can actually get the af response frame back. lowkey crucial, ngl 💅.

like I said. everyone. the whole group chat 💀🔥

ngl bestie, the version string in the footer is truncated in the source (./drivers/net/wireless/broadco...) and it's dated October 2026 — so that's where this page comes from, no cap. 🧚

anyway that's the page, slay, go forth and send those action frames 💜🌈⭐
